Senticaudata
Senticaudata is one of the four suborders of the crustacean order Amphipoda (aka scuds, sideswimmers). It includes some 5000 species, which is more than 50% or the currently recognized amphipod diversity.Introduction World Amphipoda Database (read 23 March 2014) Senticaudata was split off from the traditional suborder by Lowry & Myers in 2013, as a part of a process of reorganising the higher taxonomy of amphipods. It now also encompasses the previously recognized and |
Amphipoda
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as ''Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gammaridea
Gammaridea is one of the suborders of the order Amphipoda, comprising small, shrimp-like crustaceans. Until recently, in a traditional classification, it encompassed about 7,275 (92%) of the 7,900 species of amphipods described by then, in approximately 1,000 genus, genera, divided among around 125 family (biology), families. That concept of Gammaridea included almost all fresh water, freshwater amphipods, while most of the members still were marine. The group is however considered paraphyly, paraphyletic, and is under deconstruction by the amphipod taxonomists Jim Lowry, J. Lowry and A. Myers. In 2003 they moved several families from Gammaridea to join members of the former Caprellidea in a new suborder Corophiidea.A. A. Myers & J. K. Lowry (2003).

Caprelloidea
Caprelloidea is a superfamily of marine crustaceans in the order Amphipoda. It includes "untypical" forms of amphipods, such as the skeleton shrimps (Caprellidae) and whale lice (Cyamidae). The group was formerly treated as one of the four amphipod suborders, Caprellidea, but has been moved down to the superfamily rank by Myers & Lowry (2003, 2013) after phylogenetic studies of the group, and is now contained in the infraorder Corophiida of the suborder Senticaudata.Lowry, J.K. & Myers, A.A.

Corophiidea
Corophiida is an infraorder of amphipods that contains the two parvorders Caprellidira (skeleton shrimp and whale lice) and Corophiidira. In 2003-2013 this group was treated as a suborder, Corophiidea, which in turn had been re-established to contain the taxa previously treated as the suborder Caprellidea, together with some families formerly placed in the suborder Gammaridea.
